The Confederación Argentina — the loose confederation of interior provinces that stood in opposition to Buenos Aires from 1852 to 1861 — maintained its own financial infrastructure centered on Paraná, its provisional capital. This note was issued not by a chartered bank but directly by the national government itself, an arrangement forced by the near-total absence of functioning banking institutions in the interior provinces at the time.

The Confederación's paper issues were chronically undervalued against those circulating in Buenos Aires, and the two monetary zones operated in uneasy parallel until the reunification following the Battle of Pavón in 1861. After that, Confederación notes were effectively demonetized.
